Hello readers, I hope you all are doing great. In our previous tutorial, we discussed the implementation of pulse width modulation (PWM) in Raspberry Pi Pico using the MicroPyton programming example. We also implemented the LED brightness control program to demonstrate an application of the pulse width modulation technique.
In this tutorial, we are going to implement another application of pulse width modulation technique which is ‘Direction and position control of a servo motor’ with Raspberry Pi Pico module and MicroPython programming language.
Later in this tutorial, we will also discuss how to control the position of a servo motor with push buttons (to be used as control inputs) and also to use LEDs for indication purposes.
What is Servo Motor?
Before interfacing the servo motor with ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to set up a free media server on Raspberry Pi. We also learned how to connect with different devices and stream media files. This tutorial will teach us how to use a Raspberry pi as a DNS server.
Prerequisites
You must have access to the following resources to follow this tutorial:
Raspbian Pi OS on Raspberry Pi (2-4).
Internet access is required.
There must be a unique identifier for every machine on the Internet to speak with each other Using IP addresses; clients can identify the servers they need to contact. However, no one is expected to remember the digits of an address; thus, DNS names are used instead. This DNS can be built on a Raspberry. It's a number-to-domai ...
Hi Everyone! Glad to have you on board. Thank you for clicking this read. In this post today, I’ll cover the Role of Cloud Computing in IoT.
Digital transformation has gained momentum in the past few years, the reason traditional technologies are becoming obsolete over time. Now organizations are incorporating modern technologies into their business model at an accelerated pace. These technologies produce the influx of data and at times it becomes very difficult to process and handle that data, thanks to cloud computing that has made the handling of data easy and effective. You don’t need traditional data centers anymore to store and process information. Everything will be taken care of remotely in the cloud with data centers.
Not to mention, this is the era of automation. Companies striv ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn how to interface the PIR sensor to detect motion with the Raspberry Pi Pico module and MicroPython programming language. Later in this tutorial, we will also discuss the interrupts and how to generate an external interrupt with a PIR sensor.
Before interfacing and programming, the PIR and Pico boards let’s first have a look at the quick introduction to the PIR sensor and its working.
Fig. 1 Raspberry Pi Pico and PIR sensor
PIR motion sensor and its working
PIR stands for Passive Infrared sensors and the PIR module we are using is HC-SR501. As the name suggests the PIR or passive infrared sensor, produces TTL (transistor transistor logic) output (that is either HIGHT o ...
In this article, we will discuss the introduction to organic chemistry in which we will study organic compounds, classification of organic compounds, types of formulas, use, significances, general and covalent bond characteristics of organic compounds, and homologous series and his characteristics. 9 out of 10 takes the organic chemistry too tough but I explained it easily and simply to you. This article is for beginners and clears many topics.
Introduction to organic chemistry
Old Definition:
“The chemistry of compounds obtained from living things.”
Vital force theory
Swedish Chemist Jacob Berzelius put forward this theory in the 19th century.
State
“ Organic compounds could not be synthesized in the laboratory due to the influence of a mysterious force called vital force, which occur ...
Hello friends, I hope you all are doing well. Welcome to the 11th tutorial of our Raspberry Pi programming course. In the previous chapter, we have seen how to regulate the speed of a Stepper motor with Raspberry Pi 4. Today, we'll work on the servo motor and will control it with RPi4. So, let's get started:
Components Required:We will need the following components to control Servo Motor with Raspberry Pi 4:
Raspberry Pi 4.
Servo Motor.
Male-to-female jumper wires.
What is a servo motor?
A Servo Motor is a simple DC motor with a position feedback Control System and a gearbox.A Servo Motor's primary advantage is its ability to maintain its shaft's angular position at any desired angle i.e. if we want to keep our shaft at 67 degre ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to make a button-controlled "music box" that plays different sounds depending on which buttons are pressed. In this lesson, we will configure our raspberry pi for voice control.
What will you learn?
Like the Amazon Echo, voice-activated gadgets are becoming increasingly popular, but you can also construct your own with a Raspberry, a cheap USB mic, and some appropriate software. Simply speaking to your Raspberry Pi will allow you to search YouTube, view websites, activate applications, and even answer inquiries.
What will you need?
Because the Raspberry Pi lacks a soundcard or audio port, this project requires a USB microphone or a camera with a ...
Hi Friends! Happy to see you around. Thank you for clicking this read. In this post today, I’ll walk you through the Top 10 Workflow Automation Software.
Running a business is not an easy job. It requires a lot of deliberate effort and careful attention to run business processes successfully. Some tasks involved are repetitive and time-consuming, making it difficult for you to do them manually. This is where workflow automation comes in handy that doesn’t require human intervention and can be used to effectively manage and execute business processes.
Curious to know about Top 10 workflow automation software?

Hello readers, I hope your all are doing great. We know that a Raspberry Pi Pico module comes with multiple inbuilt features for example onboard memory, processing units, GPIOs or General Purpose Input Outputs (used to control and receive inputs from various electronic peripherals) etc.
In our previous tutorials, we discussed how to access GPIO pins of the Raspberry Pi Pico module for both input as well as output operations.
In this tutorial, we are going to discuss another important feature of the Raspberry Pi Pico module (RP2040) which is Dual Core Processor. The Pico board features with 133MHz ARM Cortex-M0+, Dual Core Processor. This dual-core feature makes the Pico module capable of multiple thread execution or multithreading.
Now before writing the MicroPython program let’s first un ...
Hi Guys! Glad to have you on board. Thank you for clicking this read. In this post today, I’ll walk you through the Types of Internet of Things (IoT).
IoT has been around for a while and has started making the headlines over the past couple of years. Some people experience IoT in their everyday life but are not aware of what it actually is. When physical objects “things” interact with the digital world, IoT is born. In simple words, it’s the network of connected devices integrated with sensors that work to exchange and share data over the internet. It is a rapidly growing technology with more than 18 billion connected IoT devices today and with the inception and boost of 5G technology this figure is expected to touch 125 billion by 2030. Experts say we may witness the stage when everythin ...
